Pickering's Triangle NGC 6974

I recently learned that the central portion of the Veil Nebula is called Pickering's Triangle a piece of which is designated NGC6974. The Veil Nebula, in constellation Cygnus, is a supernova remnant formed approximately 15,000 years ago and is about 2400 light-years distant. The source supernova was a star 20 times more massive than our Sun. It would have appeared brighter than Venus and would have been visible in daytime. [Wikipedia]. It is an often photographed deep sky object due to its intricate colorful weaving. It is of surprising astronomical beauty.

Here is my version. I pursued a new to me capture process.
Approximately 10 hours of integration was gained by shooting both rigs at the same target the same night.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
